RRB JE CE (CBT I) Mock Test- 1 - Question 1

### Two trains 165 m and 175 m long run at the speed of 50 km/h and 52 km/h respectively in opposite directions on parallel tracks. What is the time (in seconds) they take to cross each other?

Detailed Solution for RRB JE CE (CBT I) Mock Test- 1 - Question 1 Relative speed = (50 + 52) km/h = (102 x 5/18) m/s = (255/9) m/s.

Distance covered in crossing each other = (165 + 175) = 340 m.

∴ Required time = (340 x 9/255) = 12 s.

RRB JE CE (CBT I) Mock Test- 1 - Question 2

### If two equations: 2x2 - Ax - 20 = 0 and 2x2 - 11x + 12 = 0 have one root in common, then what is the value of 'A' if the value of A is positive?

Detailed Solution for RRB JE CE (CBT I) Mock Test- 1 - Question 2 2x2 - 11x + 12 = 0

(2x - 3)(x - 4) = 0

x = 1.5 and 4

Since both the equations have one root in common-

Case 1: When x = 1.5 is common-

2(1.5)2 - A(1.5) - 20 = 0

RRB JE CE (CBT I) Mock Test- 1 - Question 3

### Divya has 3 types of coins having denomination of 20p, 10p and 5p. Their numbers are in the ratio of 1: 2 : 3. If Divya has total money of Rs. 44 then how many 5p coins are there?

Detailed Solution for RRB JE CE (CBT I) Mock Test- 1 - Question 3 Since the ratio between the numbers of coins of 20p, 10p and 5p is 1 : 2 : 3 So let us assume the number of 20p coins = a

Then number of 10p coins is 2a and number of 5p coins is 3a.

Total worth of 20p coins = number of coins X worth of each coin = a X (1/5) = Rs (a/5)

Total worth of 10p coins = 2a X (1/10) = Rs (a/5)

Similarly total worth of 5p coins = 3a X (1/20) = Rs (3a/20)

Since total money with the Divya is Rs 44 hence

a/5 + a/5 + 3a/20 = 44 => 2a/5 + 3a/20 = 44

=> 8a/20 + 3a/20=44 => 11a/20 =44 => a = 80

So the number of 5p coins = 3a = 80 x 3 = 240

RRB JE CE (CBT I) Mock Test- 1 - Question 4

The difference between 42% and 23% of a number is 304. What is 72% of that number?

Detailed Solution for RRB JE CE (CBT I) Mock Test- 1 - Question 4 Let the number be 100x.

∴ 42x - 23x = 304

=> 19x = 304

=> x = 16

∴ The number is 100 x 16 = 1600.

=> 72% of the number = 0.72 x 1600 = 1152

RRB JE CE (CBT I) Mock Test- 1 - Question 5

What is the value of 60 ÷ [{21 ÷ 7 x √(√625 + √121)} − 6] x 5 - 42 ÷ 3 x 2 = ?

Detailed Solution for RRB JE CE (CBT I) Mock Test- 1 - Question 5 60 ÷ [{21 ÷ 7 x √(√625 + √121)} − 6] x 5 - 42 ÷ 3 x 2

= 60 ÷ [{3 x √(25 + 11)} − 6] x 5 - 14 x 2

= 60 ÷ [{3 x √(36)} − 6] x 5 - 28

= 60 ÷ [{3 x 6} − 6] x 5 - 28

= 60 ÷ [18 − 6] x 5 - 28

= 60 ÷ 12 x 5 - 28

= 5 x 5 - 28

= -3

RRB JE CE (CBT I) Mock Test- 1 - Question 6

Three pipes x, y and z can fill a water tanker in 20, 25 and 30 minutes respectively. All the three pipes are opened to fill the tanker and if the pipe y is closed 2 minutes before the water tanker gets filled, then in how much time will the tank get filled?

Detailed Solution for RRB JE CE (CBT I) Mock Test- 1 - Question 6 Let the time after which the water tanker gets filled be 't' minutes.

In one minute pipe x can fill 1/20 part.

In t minutes, pipe x can then fill t/20 part.

Therefore, t/20 + t-2/25 + t/30 = 1

On solving, we get t = 324/37 minutes.

RRB JE CE (CBT I) Mock Test- 1 - Question 7

If [4x - (1/12x) = 8], then what is the value of [x2 + {1/(2304x2)}] ?

Detailed Solution for RRB JE CE (CBT I) Mock Test- 1 - Question 7 4x - 1/12x = 8

=> 4(x - 1/48x) = 8

=> x - 1/48x = 2 ------ (i)

Squaring both sides, we get

(x - 1/48x)2 = 4

=> x2 + 1/(2304x2) - 2x/48x = 4 ------ [(a - b)2 = a2 + b2 - 2ab]

x2 + 1/2304 x2 = 4 + 1/24 = 97/24

RRB JE CE (CBT I) Mock Test- 1 - Question 8

A boy throws a ball of mass 4 kg vertically downwards for a height of 20 metres. What is the velocity of the ball which touches the ground? (Take g= 10 m/s2)

Detailed Solution for RRB JE CE (CBT I) Mock Test- 1 - Question 8 According to question,

Mass of ball = m = 4 kg, elevation from ground= h= 20 m; v= velocity at touch point

So, mgh = ½ (mv2)

Gives v= 20 m/s

mg = 1/2 (mv2)

2gh = v2

v2 = 2 x 10 x 20 = 400

v = 20 m/sec

RRB JE CE (CBT I) Mock Test- 1 - Question 9

=> 100x = 78.414141.. (I)

=> 10000x = 7841.414141.. (II)

(II) - (I) gives,

9900x = 7763

=> x = 7763/9900

RRB JE CE (CBT I) Mock Test- 1 - Question 10

Nidhi borrowed Rs. 10000 from a bank for a period of two years at the rate of 10% per annum. From that amount, she invested Rs. 3500 in another bank which offers simple interest @12.5% per annum and remaining amount she invested into a chit fund which offers compound interest of 10% per annum. What is the profit obtained by Nidhi at the end of two years?

Detailed Solution for RRB JE CE (CBT I) Mock Test- 1 - Question 10 Total interest that Nidhi has to pay after 2 years = Rs. (10000 x 2 x 10)/100 = Rs. 2000

Interest obtained by Nidhi from the bank = Rs. (3500 x 2 x 12.5)/100 = Rs. 875

Interest obtained by Nidhi from Chit fund = 6500(1 + 0.1)2 - 6500 = Rs. 1365

So total interest obtained by Nidhi = Rs. (875 + 1365) = Rs. 2240

Profit = Rs. (2240 - 2000) = Rs. 240
